New audio system with a sub

Hi,

As the local distributor does not import the rocco with dynaudio I changed my speakers and add a sub-woofer with two amplifiers.

The new system has 2 sets of MB-Quart 16cm mid-treble speakers. One 25cm MB-Quart sub-woofer.
One Rockford-Fosgate 4 channel amplifier for the front and rear speakers.
One 2 channel MB-Quart amplifier for the sub woofer which is used as a mono amplifier.

the sub and the rockford amplifier is from my old car.

I did not want to lose space in the trunk so we made a custom subwoofer box in the space saver spare tyre on the bottom of the trunk. It is a sealed box and removable in case the spare is needed.
It is about 15 liters and enough for 25cm subwoofer. I just lost about 4cm from the bottom of the trunk.

There are some pictures of the rear panels, empty and with the new speakers and crossovers installed. And the bottom of the trunk.

I don't think so because the tyre is in there :) the woofer is in a custom box in the tyre ! And it's easily removable

Nice Job!

I am keen to change my stock speakers but probably not to the extent you have.... just swapping the existing for something a little better. How easy is it to do?

I have seen information on how to remove the front door cards, but nothing on the rear speakers.

Great install. I'm looking to add a sub to give it a bit more depth to the sound. Don't have Dynaudio. May uprate comps at a later date depending on how the addition of just a sub sounds. Was thinking of a pre-amped under seat jobby. Couple of questions for you:

What have you done with reagrds to the HU? I assume its the stnadard unit. If so did you add a line driver or signal processor before the amps?
How easy/difficult is it to run power into the engine bay?
Did you add any soundproofing? The roc seems a bit rattley/tinny to me. Ok for standard day to day use, but when running a system could imagine it rattles a fair bit.
